Abstract
Description
Technical Field
[0001] The utility model relates to a tool head of a pneumatic tool, which is used for connecting the pneumatic tool and for loosening and tightening a target object (screw) under the drive of the pneumatic tool. Background Art
[0002] A wrench is a hand tool specially designed for tightening and loosening screws or nuts of machines and equipment. The types of wrenches on the market have quite diverse construction locations depending on demand, such as box wrenches, socket wrenches, open-end wrenches, etc., and although box wrenches and socket wrenches have better construction stability than open-end wrenches in practice, there are many cases where the two ends of the nut locking position are in a closed state, and the box wrench cannot be detached from the nut, and the socket wrench cannot be used either. Therefore, open-end wrenches are still necessary.
[0003] As for the locking of larger machines, it is more difficult to complete the locking with purely manually operated hand tools, so it is necessary to rely on pneumatic tools and electric tools to assist users in successfully locking the target object. For example, Taiwan Patent No. M634573 "Pneumatic Tools" has a defect in the application of the pneumatic wrench type on the market. That is, when completing the locking of the target object, there is a high probability that the opening of the construction head is facing inward, so that the tool head cannot be separated from the target object.
[0004] In view of the above problems, it can be known that the pneumatic tools currently on the market, when using the open-end wrench type tool head, have a high probability of completing the locking of the target object, and the opening of the construction head is facing inward and cannot be separated from the target object. Utility Model Content
[0005] In order to improve the problem that when the existing open-end wrench type pneumatic tools complete the locking of the target object, there is a high probability that the opening of the construction head is facing inward and cannot be separated from the target object, the utility model provides a tool head of a pneumatic tool, and the construction rotating part is provided with a accommodating space groove. Therefore, when the user completes the locking of the target object, if the opening of the construction rotating part is facing inward, the main body can be moved to make the target object enter the accommodating space groove from the positioning groove. At this time, continuing to operate the pneumatic tool to rotate the construction rotating part will not cause the target object located in the accommodating space groove to rotate. Therefore, it is only necessary to continue to operate the pneumatic tool until the opening of the construction rotating part is rotated from inward to outward to be separated from the target object.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] A tool head of a pneumatic tool comprises: a main body having a pneumatic tool connecting portion and an opening side; a construction rotating member arranged on the opening side of the main body, the construction rotating member having an opening, a positioning groove, and an accommodating space groove, the accommodating space groove being located between the opening and the positioning groove; and a transmission group located inside the main body and arranged between the pneumatic tool connecting portion and the construction rotating member.
[0008] Furthermore, one end of the accommodating space groove is connected to the opening, and the other end of the accommodating space groove is connected to the positioning groove.
[0009] Furthermore, the accommodating space groove of the construction rotating member is in an arc shape.
[0010] Furthermore, the construction rotating member defines an imaginary circle, the contour of the accommodating space groove is located on the circumference of the imaginary circle, and the central angle of the accommodating space groove is 70 degrees to 90 degrees.
[0011] Furthermore, the depth of the accommodating space groove of the construction rotating member is designed based on the circular range formed by the sharp point of the target object.
[0012] The beneficial effect of the present invention is that the construction rotating part is provided with a accommodating space groove, so when the user completes locking the target object, if the opening of the construction rotating part faces inward, the main body can be moved to allow the target object to enter the accommodating space groove from the positioning groove. At this time, continuing to operate the pneumatic tool to rotate the construction rotating part will not cause the target object located in the accommodating space groove to rotate. Therefore, it is only necessary to continue operating the pneumatic tool until the opening of the construction rotating part rotates from inward to outward to detach from the target object.

[0036] To understand the implementation of the present invention in more detail, please refer to the accompanying drawings. Figures 1 to 3 As presented, the utility model provides a tool head of a pneumatic tool, which includes: a main body 1, which has a pneumatic tool connecting part 11 and an opening side 12; a construction rotating part 2, which is arranged on the opening side 12 of the main body 1, and the construction rotating part 2 has an opening 21, a positioning groove 22, and an accommodating space groove 23, and the accommodating space groove 23 is located between the opening 21 and the positioning groove 22; a transmission group 3, which is located inside the main body 1 and is arranged between the pneumatic tool connecting part 11 and the construction rotating part 2.
[0037] The above are the main technical features of the main embodiment of the present utility model, which correspond to the content of claim 1 of the present utility model, so as to know the purpose and implementation form of the present utility model in detail. The technical features described in the other subsidiary claims are for elaboration of the content of claim 1 or additional technical features, rather than for limiting the scope of claim 1. It should be known that claim 1 of the present utility model does not necessarily include the technical features described in the other subsidiary claims.
[0038] The above content further describes the implementation mode of the utility model. When the utility model is actually used, Figure 4 The pneumatic tool connecting part 11 is connected to the pneumatic tool 4. In order to improve the existing problem, the utility model improves the structure of the tool head. The improvement point is that the construction rotating part 2 is provided with a receiving space groove 23, so when the user Figure 5 When the locking of the target object 5 is completed, if the opening 21 of the construction rotating member 2 faces inward, it can be as follows Figure 6 As shown, the main body 1 is moved so that the target object 5 enters the accommodating space groove 23 from the positioning groove 22. At this time, the pneumatic tool 4 is continued to be operated to rotate the construction rotating member 2. Since the accommodating space groove 23 does not have a structure that can fix the target object 5 like the positioning groove 22, the target object 5 located in the accommodating space groove 23 will not be rotated when the construction rotating member 2 rotates. In this way, it is only necessary to continue to operate the pneumatic tool 4 until the opening of the construction rotating member 2 is opened. Figure 7 , Figure 8 It is shown that the target object 5 can be detached by rotating from inward to outward. Combining all the above contents, it can be known that the utility model does improve the existing open-end wrench type pneumatic tool 4 in that when completing the locking of the target object 5, there is a high probability that the opening of the construction head is facing inward and cannot be detached from the target object. The utility model is indeed novel and progressive.
[0039] Furthermore, one end of the accommodating space groove 23 is connected to the opening 21 , and the other end of the accommodating space groove 23 is connected to the positioning groove 22 .
[0040] Furthermore, the accommodating space groove 23 of the construction rotating member 2 is in an arc shape, which can avoid to the greatest extent that the wall surface of the accommodating space groove 23 drives the locked target object 5 during the rotation of the construction rotating member 2.
[0041] Further Figure 3 As presented, the construction rotating part 2 defines an imaginary circle C, the contour of the accommodating space groove 23 is located on the circumference of the imaginary circle C, and the central angle θ of the accommodating space groove 23 is 70 degrees to 90 degrees, and the preferred central angle θ is 80 degrees. If the central angle θ is too large, the range of the positioning groove will be too small, so that the positioning groove 22 will have difficulty in driving the target object 5 to rotate, and if the central angle θ is too small, the accommodating space groove 23 will not have enough space for the target object 5 to avoid being driven by the wall of the positioning groove 22. Therefore, a central angle θ of 70 degrees to 90 degrees is a more appropriate configuration.
[0042] Furthermore, the depth D of the accommodating space groove 23 of the construction rotating part 2 is designed based on the circular range formed by the sharp points of the target object 5 (for example, if the target object 5 is in the form of a hexagonal nut, the design is based on the circular range formed by the six sharp points of the target object 5, and the imaginary circle C will be slightly larger than the circular range formed by the sharp points of the target object 5. In this way, during production, the required correct depth D can be obtained according to the above conditions in combination with the size of the target object 5 and the wall thickness of the construction rotating part 2).
[0043] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
